To all 'whom it may eoizcem:

Be it known that I, PAUL R. SnuMoNs,a citizen of the United States, and a resident of Marion, in the'county of Grant and State of Indiana, haveinvented certain new and useful Improvements in Dish-Forming Maf chincs, of which the following'is a specificatlon.

`My present invention relates to an im- 4proved machine for forming paper dishes or pie-plates and more particularly to a machine 'of this character which' is adapted to be used in connection with a rotary cutting device and to receive the paper therefrom, such a cutting device as described and claimed in my Patent No. 1,044,931, dated November 19, 1912.

The primary object of this vinvention is to vprovide a machine which will automatically These objects, and certa-in -others which will be apparent, with their resulting advantages, I attain by means of the structure to be now described with reference to the accompanying drawing, in which,

Figure 1 is a vertical transverse sectional vview taken substantially on lineY 1-1 of. Fig. 2. Fig. 2 is awvertical longitudinal sectional view taken substantially on line 2 2 of Fig. 1. Fig. 3 is a horizontal section taken substantially on line 3-3 of Fig. 1. Fig. 4 is a side elevation of the complete apparatus. Fig. 5 is a plan view vof a. portion of the partially cut web or sheet, and, Fig. 6 is a sectional detail of one cf the waste breaking plungers. A

Referring now to these figures, the frame A of my improved machine embodies a substantially U-shaped upper portion and a .base upon the :forward` portion of which is formed a shelf adapted, as clearly shown in Fig. 2 to support the cutting device. This cutting Vdevice being fully described my patent above referred to, it will suiice here to say that it embodies superposed rollers, one of which is provided with circular cut-V ting edges on its periphery so that by lproper relative adjustment of the rollers, a sheet 'or web of paper fed therebetween, may be partally cut 11p-into disks. This cutting device is shown in dotted lines in Figs. 2 and 4 and the web B, partially cut and before be- 1ng pressed to shape, is shown in detail in Fig. 5.

From the cutting machine, the web B is automatically fed into the forming machine above the skeleton bed plate C and the female dies C supported thereon and in passing thereover is subject to the combined action of these female dies'C and the male dies D and also to the action of the wastebreaking plungers.

The dies C and D are hollow as particularly shown in Fig. 1 andcentrally braced, the female dies C having central springcontrolled plungers c by which the-plates when formed are lifted. and may thus be discharged by succeeding portions of the web B." These hollow dies receive a constant supply of steam or other heating agent through pipes F and F', the latter, which communicates with the male dies being flexible in order to allow for the necessary movement of these dies.

The upwardly extending cylindrical stems -D of the male dies are journaled through bearings g in a. guide frame G rigidly connected between the side portions of the frame A, the upper ends of these stems receiving the lower ends of the rods L depending from the carriage H', the latter slidingon the frame ribs a under actuation of the pitmen i extending from the cranks i of the crank shaft I. The stems D have transverse slots through which extend pins 71.2 carried by rod's la., the lower ends'of the latter bearing on springs d. within the stems whereby to form a cushion.

-The waste-breaking plungers are in the form of spring-controlled rods y', the lower heads J of which are generally triangular and of the particular shape shown in Fig. 6, these rods extending through bearing tubes g vin the guide frame G and having their upper angular extremities j' adapted to be engaged by angularly extending members l: of arms K depending from the carriage H, when the carriage moves upwardly in order to raise the Waste-breaking plungers and put their springs 7'2 under tension. The plungers are heldin an upper position by triggers j; which the members c engage and release upon the downward movement of carriage H whereby the plungers are free to descend under actuation of their springs and break out the triangular portions b of the web B between the disks at the time the latter are clamped between the dies and pressed into shape as shown in Fig. 3.

One outer end of the crank shaft I is provided with a gear wheel I which is connected to the driving gear L through an intermediate gear L', the latter also transmitting power to the cutting device whereby the web B may be properly fed and the two operations relatively timed. It will thus be seen that as the power is applied, the partially out web of paper or pulp'stock in a moist or somewhat green state will be automatically fed from the cutting device between the forming dies and that the carriage will lower to clamp and form the partially cut disks between the dies, at which time the plungers J will be tripped and allowed `to descend, breaking out the waste material between the disks and discharging the same downwardly between the female dies. Then the carriage H rises the formed plates as shown in Fig. 3 will be thrust upwardly by the plungers c and discharged "by the oncoming web B. It will be further seen that during the forming operation between the dies, and by virtue of the fact that these dies are supplied with sullicient and constant heat through the means before described, the plates will be cured and thus their shape will be preserved.

I claim:

l. In a paper plate forming machine, the combination of means for feeding a sheet of partially cut disks, means for stamping out and curing the plates, and means for stamping out the waste material between the several plate disks.

2. In a paper plate forming machine, the combination' of sheet feeding means, dies for stamping circular formed plates therefrom, and waste breaking plungers to stamp out waste material from between the plates, movable with respect to the dies when the latter are in clamped positions on the plates.

3. In ay paper plate forming machine, dies for stamping circular formed plates from a lsheet, a frame in which certain of the dies are supported, a carriage sldable in the frame for moving others of the dies', waste breaking plungers mounted in the frame, means for moving the plungers with respect to the dies movable with the carriage, and

means actuated by the carriage for controlling movement of the said plungers.

4. In a paper plate forming machine, the combination of means for feeding a sheet of partially cut disks, sets of opposing dies for clamping the sheet ybetween them andl shaping the disks, and spring actuated plungers controlled by movement of the dies and movable against the sheet when the dies are clamped thereon to stamp out the waste material between the disks, all substantially as described.

5. The combina-tion of male and female dies for pressing paper to form plates, a frame in which the female dies are supported, a carriage slidable in the frame for moving the male dies, spring-actuated plungers mounted in the frame to stamp out the waste material between the plates, and means movable with the carriage for controlling said plungers.
